Imgbox Modifiers - Honeywell Xenon 1910 User Manual

Below is an example of a signature capture application. In this example, the aimer is centered over the signature capture area
and the trigger is pressed. A single beep is emitted, indicating that the scanner has read a Code 128 bar code and the data has
been transferred to the host. If using a Granit scanner, the scanner also vibrates. An IMGBOX command may now be sent
from the host to specify the coordinates of the signature capture area below that code, and indicating that only that area contain-
ing the signature should be transferred as an image to the host.
To see this example, align the aimer with the signature area (not with the bar code), then press the trigger.
Send the following IMGBOX command string after the button push:
Example: IMGBOX245w37h55y.
Note: Case is not important in the command string. It is used here only for clarity.
The following image is captured:
The IMGBOX commands have many different modifiers that can be used to change the size and appearance of the signature
image output by the scanner. Modifiers affect the image that is transmitted, but do not affect the image in memory. Any number
of modifiers may be appended to the IMGBOX command.
Note: The IMGBOX command will return a NAK unless a window size (width and height) are specified. See
